for exact word matches, try:
Code:
awk '
NR==FNR {a[$1]=$1; next;}
{l=0; for (i=1; i<=NF; i++) if ($i in a) {print ; next;}}
' words_file infile

for exact word match count of 1 (as shown), try:
Code:
awk '
NR==FNR {a[$1]=$1; next;}
{l=0; for (i=1; i<=NF; i++) ($i in a) ? l++ : 0; if (l==1) print}
' words_file infile

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
